System and method for measuring distance between side walls of segment steel die

Abstract

The invention relates to a system and method for measuring the distance between side walls of a segment steel die. The system comprises an operating rod, laser range finders and a calculation module,wherein the operating rod is arranged between two side walls, and the end part of the operating rod is opposite to the side walls; the laser range finders are mounted at the two ends of the operatingrod and can emit laser to the corresponding side walls, and the laser emitted by the two laser range finders is parallel to the axis of the operating rod so as to measure the distances from the two laser range finders to the corresponding side walls; and the calculation module is arranged on the operating rod and is used for calculating the distance between the two side walls according to the distances from the two laser range finders to the corresponding side walls and the length of the operating rod. The problem that the distance between the side walls of the segment steel die is inconvenient to measure is effectively solved, the influence of human factors on the measurement result is reduced, the operation is convenient, the detection speed is high, the detection precision is high, andthe production quality of segments can be guaranteed.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a measuring system and a measuring method for the distance between side walls of a segment steel mold. Background technique [0002] Segment is an important element of tunnel quality. Segment accuracy directly affects the quality of segment assembly and the structural performance of the tunnel after forming. It also involves its waterproof performance and durability. The most important factor affecting the quality of segment production is Segment Steel Mold. [0003] According to the segment production process, the four sides of the steel mold must be closed in place first, and then the cement can be injected to form the segment. Therefore, whether the steel mold is closed in place must be strictly controlled. Mold produces errors. At present, most of them use large calipers and simple measuring tools to detect the mold closing distance and judge the steel mold clamping status...
